Enhanced Audio and Video Synchronization

Enhanced Audio and Video Synchronization provides improved full-screen video playback, reducing the difference in delays between the audio and video channels and smoothing frame playback on the client. This improves lip sync and reduces video frame drops for movie playback.

This feature introduces a small lag in user interaction responsiveness when enabled. Using enhanced audio and video synchronization will reduce the maximum frame rate.

Enhanced A/V Sync is enabled on a per-display basis, so you can dedicate individual displays to playback without impacting responsiveness on the others.

To turn on A/V Sync:

  1. Execute the following command:

    defaults write "com.teradici.Teradici PCoIP Client.plist" enable_enhanced_avsync 1
    The above text is OS specific. Note the setting changed from 0 to 1 in the 19.11 release of the PCoIP Client.

  2. You need to reboot your system for this change to take effect.

When enabled, a check mark will appear beside the enhanced A/V Sync menu item on that display. It is disabled on all displays by default.

To use enhanced A/V Sync:

  1. If you are in full-screen mode, reveal the menu bar on the display you want to enhance by moving the mouse cursor to the top of the screen.
  2. On the display you want to enhance select View>Enhanced A/V Sync to toggle the enhanced sync mode.

Persistent Display Topology

The Enhanced Audio and Video Synchronization feature is persistent across sessions from the same client, provided that the display topology has not changed.
